A/N: So this is just a sort of conclusion that I decided to add on. You're free to ignore it if you wish, however, and count this out in the... continuity-of-sorts.
Deidara,
By the time you read this, I will have been reduced to the same wooden, motionless state as you are, only with a gaping hole in my chest. I am aware that you cannot even read, but… well, I just need to get this out somehow.
You should've seen how livid Sir Leader was when he discovered the deaths of you and Itachi. Kisame became pretty much useless after I killed Itachi - they say those two were deeply close friends. Needless to say, Sir Leader realised that all these petty relationships began when he and Konan started being open about theirs. He thus decided to punish me and Kisame with execution before disbanding Akatsuki. I'm currently hunched over my work bench in the worst pain imaginable - and to make matters worse, my emotions filter seems to have worn off. Any moment now, I may die and leave this letter incomplete, so I am writing as fast as my body will allow me to.
As it turns out, I do in fact love you. That love was buried deep into my heart, where I wasn't able to find it until I regained emotions. All of the things I have done in the past 15 years, I now regret. But most of all, I regret killing you.
I wish I didn't have to say this, but… you never actually loved Itachi. He used a genjutsu to delude you into loving him. I realise that perhaps the one your heart truly desired was Tobi, but… he's really Itachi's grandfather or something, you know. Or so Itachi says. Maybe he was bluffing. No way I can find out for sure now. Either way, I now know that when you're in love, and you're a puppet, a disaster will easily brew. So I apologise for the trouble I have caused.
I honestly wish that I can undo these past 15 years. But I cannot, and they will stay with me forever. If I never became a puppet, I might've never met you. Funny, that. If I had the means, I'd be weeping right now. You know what they say… love makes you crazy.
You were right. Art is fleeting. And so am I, in the end. Not even I can be eternal.
So I guess I'll see you in Hell, Deidara. I know you'll never love me in any lifetime, no matter what, but… I do love you.
